The speaker device includes wiring electrically connected to the voice coil, an electronic component having a component wire, and a frame. The frame has a conductive wire fixing part for fixing the conductive wire, and the conductive wire is fixed to the conductive wire fixing part to be directly connected to the wiring. Thereby, even if a vibration is transmitted to the frame at the time of driving the speaker device, the conductive wire never vibrates, and the conductive wire does not pull the wiring. Therefore, the conductive wire and wiring are not cut. Also, since the conductive wire is the speaker terminal lug, cost of the speaker device can be reduced.

TECHNICAL FIELD

The present invention relates to a wiring configuration of a speakerdevice.

BACKGROUND TECHNIQUE

Conventionally, there is known a speaker device having a wiringconfiguration of electrically connecting a tinsel cord electricallyconnected to a lead wire of a voice coil or the voice coil and wiringdrawn from an amplifier via a terminal lug for a speaker device.

In the speaker device having the wiring configuration, the lead wire ofthe electronic component having such a function is sometimeselectrically connected to the terminal lug for the speaker device inorder to control a frequency component of a sound signal inputted to thevoice coil via the wiring of the amplifier (see Patent References-1 to3, for example). As the electronic component, there are a capacitor, acoil, a resistor and the like.

In the speaker device according to Patent References-1 to 3, a capacitoris mounted on a capacitor mounting part provided on a frame or a storagepart provided in a connector, and the lead wire of the capacitor iselectrically connected to a tinsel cord via the terminal lug for thespeaker device. In Patent References-1 and 2, the capacitor mountingpart is referred to as “clamp part” and “mounting part”, and theterminal lug for the speaker device is referred to as “terminal” and“terminal board”, respectively.

Namely, the terminal lug for the speaker device is provided in thespeaker device, and the lead wire of the capacitor and the lead wire orthe tinsel cord of the voice coil are not directly connected.

In a speaker device according to Patent Reference-4, the above-mentionedelectronic component (referred to as “network electronic component” inPatent Reference-4) is provided, and a protective cover to which theelectronic component is fixed is mounted on a back side of the frame(i.e., on a side reverse to an acoustic radiation side).

Patent Reference-2: Japanese Patent Application Laid-open under No.2000-152395

DISCLOSURE OF INVENTION Problem to be Solved by the Invention

In the above-mentioned speaker device according to Patent References-1to 3, the terminal lug for the speaker device is provided in order toelectrically connect the lead wire of the capacitor and the tinsel cord.Thus, the cost of the speaker device problematically increases by thecost of the additional terminal lug.

Additionally, in the speaker device, the capacitor, inserted into aninsertion hole of the capacitor mounting part, is mounted on thecapacitor mounting part. Therefore, the capacitor is not so stronglyfixed to the capacitor fixing part. Thus, the speaker device of thiskind has problems, which will be described now. Namely, if a vibrationoccurring at the time of driving the speaker device is transmitted tothe capacitor via the frame, the capacitor vibrates due to thevibration, and the capacitor considerably moves with respect to apredetermined mounting position of the capacitor mounting part or slipswith respect to the capacitor mounting part. At this time, the capacitorpulls the lead wire of the capacitor. Thereby, the lead wire of thecapacitor is problematically cut. Further, an external force operates onthe connection part of the lead wire of the capacitor and the tinselcord, and the joint part breaks. As a result, the lead wire of thecapacitor and the tinsel cord may be problematically cut.

In view of these problems, if the lead wire of the capacitor and thewiring (the tinsel cord or the lead wire of the voice coil) electricallyconnected to the voice coil can be directly connected, it becomesunnecessary to provide the terminal lug for the speaker device.Therefore, the increase in the cost of the speaker device can beprevented.

However, when the configuration is employed, the vibration occurring atthe time of driving the speaker device is transmitted to the capacitorvia the frame, and the lead wire of the capacitor pulls the wiringelectrically connected to the voice coil. Thereby, the lead wire of thecapacitor and the wiring electrically connected to the voice coil areproblematically cut, and the joint part of the lead wire of thecapacitor and the wiring electrically connected to the voice coil andthe connection part of the voice coil and the wiring electricallyconnected to the voice coil are problematically cut. So as to solvethese problems, it is thought that a lead wire fixing part for fixingthe lead wire of the capacitor is further provided, and the lead wire ofthe electronic component is fixed.

The present invention has been achieved in order to solve the aboveproblems. It is an object of this invention to provide a speaker devicehaving a wiring configuration capable of preventing cut of wiringelectrically connected to a conductive wire of an electronic componentand a voice coil and capable of electrically connecting the conductivewire of the electronic component and the wiring electrically connectedto the voice coil without a speaker terminal lug.

In the invention according to claim 1, a speaker device includes: wiringelectrically connected to a voice coil; an electronic component having aconductive wire; and a supporting body for supporting the voice coil andthe electronic component, wherein the supporting body has a conductivewire fixing part for fixing the conductive wire of the electroniccomponent, wherein the conductive wire of the electronic component isfixed to the conductive wire fixing part of the supporting body to bedirectly connected to the wiring of the voice coil.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

According to one aspect of the present invention, there is provided aspeaker device, including: wiring electrically connected to a voicecoil; an electronic component having a conductive wire; and a supportingbody for supporting the electronic component, wherein the supportingbody has a conductive wire fixing part for fixing the conductive wire ofthe electronic component, wherein the conductive wire of the electroniccomponent is fixed to the conductive wire fixing part of the supportingbody to be directly connected to the wiring.

The above speaker device includes the wiring electrically connected tothe voice coil, the electronic component having the conductive wire(hereinafter referred to as “lead wire”), and the supporting body forsupporting the electronic component. The wiring electrically connectedto the voice coil is the lead wire of the voice coil or the tinsel cordelectrically connected to the lead wire of the voice coil. In addition,“electronic component” is the capacitor, the coil and the resistor, forexample. The electronic component controls the frequency component ofthe sound signal inputted to the voice coil via wiring (not shown) ofthe amplifier, and adjusts the input level of the sound signal.

Particularly, in the speaker device, the supporting body has theconductive wire fixing part for fixing the conductive wire of theelectronic component, and the conductive wire of the electroniccomponent is fixed to the conductive wire fixing part of the supportingbody to be directly connected to the wiring.

Thereby, even if the vibration is transmitted to the supporting body atthe time of driving the speaker device, the conductive wire of theelectronic component never vibrates or moves. Therefore, it can beprevented that the conductive wire of the electronic component pulls thewiring of the voice coil. Hence, it can be prevented that the conductivewire of the electronic components and the wiring of the voice coil arecut. In addition, since the wiring of the voice coil is never pulled onthe side of the conductive wire of the electronic component, it can beprevented that the voice coil is pulled on the side of the conductivewire of the electronic component. Therefore, at the time of driving thespeaker device, it can be prevented that the movement (the vibrationoccurring in the case that the sound current is inputted) of the voicecoil is prevented.

By the configuration, the conductive wire of the electronic componentserves as the speaker terminal lug. Thus, the conductive wire of theelectronic component and the wiring of the voice coil can beelectrically connected without the speaker terminal lug included in theabove-mentioned speaker device according to Patent References-1 to 3.Thereby, the cost of the speaker device can be reduced by the cost ofthe additional terminal lug.

In a manner of the above speaker device, the supporting body may includeplural electronic component fixing parts for fixing the electroniccomponent, and the electronic component may be fixed to the electroniccomponent fixing part.

Thereby, even if the vibration is transmitted to the supporting body atthe time of driving the speaker device, the electronic component neverpulls the conductive wire of the electronic component. Therefore, theconductive wire of the electronic component never vibrates or moves.Thereby, it can be prevented that the conductive wire of the electroniccomponent pulls the wiring of the voice coil. Therefore, it can beprevented that the conductive wire of the electronic component and thewiring of the voice coil are cut.

In another manner of the above speaker device, a first conductive wireguide part for guiding the wiring of the electronic component to theconductive wire fixing part may be provided between the electroniccomponent fixing part and the conductive wire fixing part. Theconductive wire fixing part may have: an insertion hole for insertingthe conductive wire; a groove for fixing a end portion of the conductivewire; and a second conductive wire guide part, provided between theinsertion hole and the groove, for guiding the conductive wire from theinsertion hole to the groove. The insertion hole and the groove maysandwich the second conductive wire guide part to be arranged oppositeto each other. The conductive wire drawn from the electronic componentmay be guided to the insertion hole along a back surface of the firstconductive wire guide part positioned in a direction reverse to theacoustic radiation direction; may be bent in the acoustic radiationdirection to be inserted to the insertion hole; may be drawn to asurface of the second conductive wire guide part positioned in theacoustic radiation direction; and may be guided to the groove along thesurface of the second conductive wire guide part. The end portion of theconductive wire may be bent in the direction reverse to the acousticradiation direction to be fixed into the groove.

In this manner, the first conductive wire guide part for guiding theconductive wire of the electronic component to the conductive wirefixing part is provided between the electronic component fixing part andthe conductive wire fixing part. Then, the conductive wire fixing parthas: the insertion hole for inserting the conductive wire of theelectronic component; the groove for fixing the end portion of theconductive wire of the electronic component; and the second conductivewire guide part, provided between the insertion hole and the groove, forguiding the conductive wire of the electronic component from theinsertion hole to the groove. In addition, the insertion hole and thegroove sandwich the second conductive wire guide part to be arrangedopposite to each other.

The conductive wire drawn from the electronic component is guided to theinsertion hole along the back surface of the first conductive wire guidepart positioned in the direction reverse to the acoustic radiationdirection; is bent in the acoustic radiation direction to be inserted tothe insertion hole; is drawn to the surface of the second conductivewire guide part positioned in the acoustic radiation direction; and isguided to the groove along the surface of the second conductive wireguide part. The end portion of the conductive wire of the electroniccomponent is bent in the direction reverse to the acoustic radiationdirection to be fixed into the groove. In a preferred example, thewiring is directly and electrically connected to the conductive wire ofthe electronic component drawn to the surface of the second conductivewire guide part.

Therefore, the conductive wire of the electronic component is fixed bythe insertion hole and the groove provided at the position opposite tothe insertion hole with sandwiching the second lead wire guide part.Thereby, even if the vibration is transmitted to the supporting body atthe time of driving the speaker device, the conductive wire of theelectronic component never vibrates or moves. Thus, it can be preventedthat the conductive wire of the electronic component pulls the wiring ofthe voice coil. Therefore, it can be prevented that the conductive wireof the electronic component and the wiring of the voice coil are cut.

In still another manner of the above speaker device, a projecting bentpart for bending the conductive wire of the electronic component in apredetermined direction may be provided on a back surface of theelectronic component fixing part positioned in the direction reverse tothe acoustic radiation direction or on the back surface of the firstconductive wire guide part, and the conductive wire drawn from theelectronic component may be bent in a direction of the insertion hole atthe projecting bent part to be guided to the insertion hole along theback surface of the first conductive wire guide part.

In this manner, the projecting bent part for bending the conductive wireof the electronic component in the predetermined direction is providedon the back surface of the electronic component fixing part positionedin the direction reverse to the acoustic radiation direction or on theback surface of the first conductive wire guide part. The conductivewire drawn from the electronic component is bent in the direction of theinsertion hole at the projecting bent part, and is guided to theinsertion hole along the back surface of the first conductive wire guidepart. Thereby, in some shapes of the supporting body, even when theconductive wire drawn from the electronic component, straightlyextending, cannot be guided to the insertion hole because of possibilityof short circuit with the conductive wire, it becomes possible that theconductive wire drawn from the electronic component is bent in thedirection of the insertion hole by the projecting bent part, and isrounded to be securely guided into the insertion hole. Additionally, inthis manner, the conductive wire drawn from the electronic componentcontacts the bent part to be bent. Therefore, by dispersing thevibration energy transmitted from the supporting body to the bent part,it can be suppressed that the vibration energy is transmitted to theelectronic component fixing part. Also, it can be suppressed that theelectronic component slips from the electronic component fixing part.

In still another manner of the above speaker device, the electroniccomponent may have a pair of conductive wires; a pair of projecting bentparts for bending the conductive wire of the electronic component in apredetermined direction may be provided on the back surface of theelectronic component fixing part positioned in the direction reverse tothe acoustic radiation direction or on the back surface of the firstconductive wire guide part; and the pair of conductive wires drawn fromthe electronic component may be bent in the predetermined direction atthe pair of projecting bent parts, respectively.

In this manner, the electronic component has the pair of conductivewires. The pair of projecting bent parts for bending the conductive wireof the electronic component in the predetermined direction are providedon the back surface of the electronic component fixing part positionedin the direction reverse to the acoustic radiation direction or on theback surface of the first conductive wire guide part. The pair ofconductive wires drawn from the electronic component are bent in thepredetermined direction at the pair of projecting bent parts,respectively. Therefore, it can be prevented that the short circuitoccurs between the wiring of the voice coil and the conductive wire ofthe electronic component by the pair of projecting bent parts providedwith the predetermined space.

In still another manner of the above speaker device, the conductive wirefixing part may have a conductive wire fixing hole, penetrating in theacoustic radiation direction, for fixing the bent conductive wire of theelectronic component. A conductive wire supporting part, having astep-state cross-section and supporting the end portion of theconductive wire, may be provided in the conductive wire fixing hole. Theconductive wire drawn from the electronic component may be guided to theconductive wire fixing hole along the back surface of the electroniccomponent fixing part positioned in the direction reverse to theacoustic radiation direction; may be bent in the acoustic radiationdirection to be inserted to the conductive wire fixing hole; and may bearranged into the conductive wire fixing hole to form a projecting shapein the acoustic radiation direction. The end portion of the conductivewire may be supported by the conductive wire supporting part in theconductive wire fixing hole. The conductive wire arranged in theconductive wire fixing hole may be fixed by the conductive wiresupporting part and a surface opposite to the conductive wire supportingpart. The conductive wire of the electronic component positioned in theacoustic radiation direction may be directly connected to the wiring ofthe voice coil at a position corresponding to the conductive wire fixinghole.

In this manner, the conductive wire fixing part has the conductive wirefixing hole, penetrating in the acoustic radiation direction, for fixingthe bent conductive wire of the electronic component. The conductivewire supporting part, having the step-state cross-section and supportingthe end portion of the conductive wire of the electronic component, isprovided in the conductive wire fixing hole.

The conductive wire drawn from the electronic component is guided to theconductive wire fixing hole along the back surface of the electroniccomponent fixing part positioned in the direction reverse to theacoustic radiation direction; is bent in the acoustic radiationdirection to be inserted to the conductive wire fixing hole; and isarranged into the conductive wire fixing hole to form the projectingshape in the acoustic radiation direction. The end portion of theconductive wire of the electronic component is supported by theconductive wire supporting part in the conductive wire fixing hole. Theconductive wire of the electronic component arranged in the conductivewire fixing hole is fixed by the conductive wire supporting part and thesurface opposite to the conductive wire supporting part. The conductivewire of the electronic component positioned in the acoustic radiationdirection is directly connected to the wiring of the voice coil at theposition corresponding to the conductive wire fixing hole.

Thereby, even when the space for fixing the conductive wire at thesupporting body is not so enough, the conductive wire of the electroniccomponent can be securely fixed into the conductive wire fixing hole.

By the configuration, the conductive wire of the electronic componentserves as the speaker terminal lug. Therefore, the conductive wire ofthe electronic component and the wiring of the voice coil can beelectrically connected without the speaker terminal lug included in theabove-mentioned speaker device according to Patent References-1 to 3.Thereby, the cost of the speaker device can be reduced by the cost ofthe additional terminal lug.

By the configuration, even if the vibration is transmitted to thesupporting body at the time of driving the speaker device, theconductive wire of the electronic component never vibrates or moves.Thus, it can be prevented that the conductive wire of the electroniccomponent pulls the wiring of the voice coil. Therefore, it can also beprevented that the conductive wire of the electronic component and thewiring of the voice coil are cut. In addition, since the wiring of thevoice coil is never pulled on the side of the conductive wire of theelectronic component, it can be prevented that the voice coil is pulledon the side of the conductive wire of the electronic component.Therefore, at the time of driving the speaker device, it can besuppressed that the appropriate movement of the voice coil is prevented.

In still another manner of the above speaker device, a connection partbetween the conductive wire of the electronic component and the wiringof the voice coil may be soldered. Thereby, the wiring of the voice coilcan be securely electrically connected to the conductive wire of theelectronic component.

In still another manner of the above speaker device, the conductive wireof the electronic component positioned in the insertion hole and/or thegroove may be fixed via an adhesive applied to the insertion hole and/orthe groove. Thereby, the joint force of the insertion hole of thesupporting body and/or the groove and the conductive wire of theelectronic component can be enhanced.

In still another manner of the above speaker device, the supporting bodymay be made by a resin material. Thereby, forming the supporting bodybecomes easy.

(Configuration of Frame)

The frame 4 having a bowl shape has a function to support the magneticcircuit 30 and the vibration body 31. The frame 4 is preferably made bya resin material. Thereby, forming of the frame 4 becomes easy. Thedetailed configuration of the frame 4 will be explained later.

(Configurations of Other Components)

As the other components, there are the sound absorbing material 9, thecapacitor 10, the speaker terminals 11 a and 11 b and the annular member12, and configurations thereof will be described below.

The sound absorbing material 9, having permeability, is mounted on theupper end surface 71 b of the first member 71 of the damper 7. At thetime of driving the speaker device 100, the sound absorbing material 9absorbs most of the unnecessary sound wave occurring on the back side(on the side reverse to the acoustic radiation direction Y1) of thesound outputting part 8 a of the diaphragm 8. Namely, the soundabsorbing material 9 has a function to prevent deterioration of soundquality.

The capacitor 10 has a pair of lead wires (conductive wires) 10 a and 10b, which are fixed to a capacitor fixing part 43 b of the frame 4.

(Configuration of Wiring Circuit of Speaker Device)

Next, a description will be given of the configuration of the wiringcircuit of the speaker device 100 with reference to FIGS. 1A and 1B toFIG. 3. FIG. 3 schematically shows a wiring circuit 90 of the speakerdevice 100.

The speaker device 100 includes the capacitor 10 and a speaker main body60 (including a vibration body 31, the magnetic circuit 30 and the frame4) between the speaker terminals 11 a and 11 b, which are connected inseries.

Thereby,based on Fleming's left-hand rule, an electromagnetic force (Lorentz'sforce) operates on the voice coil 6 in the magnetic gap 32. Then, thevoice coil 6 and the diaphragm 8 move together in the acoustic radiationdirection Y1 and the reverse direction. Thereby, the sound wave isoutputted in the acoustic radiation direction Y1 via the soundoutputting part 8 a of the diaphragm 8.

FIG. 4A shows a front view of the frame 4 positioned in the acousticradiation direction Y1. FIG. 45 shows a rear view of the frame 4positioned in the direction reverse to the acoustic radiation directionY1. FIG. 5A shows a cross-sectional view along a cutting line C-C′passing through the central line L1 of the frame 4 shown in FIG. 4A, andit particularly shows a cross-sectional view when the frame 4 is cut ata position passing through plural speaker terminal mounting parts 43 a.FIG. 5B shows a cross-sectional view along a cutting line D-D′ passingthrough the central axis L1 of the frame 4 shown in FIG. 4A, and itparticularly shows a cross-sectional view when the frame 4 is cut at aposition passing through the capacitor fixing part 43 b to which thecapacitor 10 is fixed.

The basic configuration of the frame 4 is described above. The frame 4includes a plate-shaped mounting part 41, a cylindrical part 42 whichextends to the acoustic radiation direction Y1 from the outer peripheralpart of the mounting part 41, and a brim-shaped flange part 43 whichextends to the direction substantially orthogonal to the central axis L1and on the outer side with respect to the upper end part of thecylindrical part 42.

A penetration hole 41 a penetrating in the direction of thecentral axis L1 is provided at the center of the mounting part 41. Apenetration hole 41 a has a function to emit the heat, generated in thevoice coil 5 at the time of driving the speaker device 100, to theexternal via the magnetic circuit 30.

As shown in FIG. 2, the cylindrical part 42 surrounds the outerperipheral part of the magnetic circuit 30, and protects the magneticcircuit 30.

FIG. 6B shows the fixing configuration of the leadwire 10 a of the capacitor 10 corresponding to the vicinity of thebroken-lined area 52 shown in FIG. 1B.

Hereinafter, the pair of lead wires 10 a and 10 b drawn from thecapacitor 10 will be explained.

Now, the fixing configuration of the lead wire 10 a of the capacitor 10at the lead wire fixing part 43 k will be explained.

The capacitor 10 accommodated in the opening 43 ba is fixed to thecapacitor fixing part 43 b. The lead wire 10 a drawn from the capacitor10 is guided from the back surface 43 x of the capacitor fixing part 43b to the bent part 43 gc positioned on the outside with respect to thecentral axis L1, of the pair of the bent parts 43 gc provided on theback surface 43 x of the first lead wire guide part 43 ga. Then, thelead wire 10 a is outwardly bent at the one of the bent parts 43 gc, andis further guided to the insertion hole 43 h along the back surface 43 xof the first lead wire guide part 43 ga. The lead wire 10 a of thecapacitor 10 is bent in the acoustic radiation direction Y1 to beinserted to the insertion hole 43 h, and is drawn to the surface 43 y ofthe second lead wire guide part 43 gb, positioned in the acousticradiation direction Y1, to be guided to the groove 43 d along thesurface 43 y of the second lead wire guide part 43 gb. The end portion10 aa of the lead wire 10 a of the capacitor 10 is bent in the directionreverse to the acoustic radiation direction Y1 to be fixed to the groove43 d. Therefore, the lead wire 10 a of the capacitor 10 is fixed to theinsertion hole 43 h and the groove 43 d opposite to the insertion hole43 h, both of which sandwich the second lead wire guide part 43 gb.

The fixing configuration of the lead wire 10 a of the capacitor 10 atthe above-mentioned lead wire fixing part 43 k may be reinforced via theadhesive so that the lead wire 10 a of the capacitor 10 is more stronglyfixed to the lead wire fixing part 43 k.

In a preferable example, the lead wire 10 a of the capacitor 10,positioned on the back surface 43 x of the capacitor fixing part 43 band/or the back surface 43 x of the first lead wire guide part 43 ga, ispreferably fixed via an adhesive (not shown) applied to the back surface43 x of the capacitor fixing part 43 b and/or the back surface 43 x ofthe first lead wire guide part 43 ga. Thereby, it becomes possible toenhance the joint force between the back surface 43 x of the capacitorfixing part 43 b and/or the back surface 43 x of the first lead wireguide part 43 ga and the lead wire 10 a of the capacitor 10.

In addition, it is preferable that the adhesive (not shown) is appliedto the insertion hole 43 h and the lead wire 10 a of the capacitor 10positioned at the insertion hole 43 h is fixed into the insertion hole43 h via the adhesive. Thereby, it becomes possible to enhance the jointforce between the insertion hole 43 h and the lead wire 10 a of thecapacitor 10.

In addition, the lead wire 10 a of the capacitor 10 positioned on thesurface 43 y of the second lead wire guide part 43 gb is preferablyfixed by the adhesive (not shown) applied to the surface 43 y of thesecond lead wire guide part 43 gb. Thereby, it becomes possible toenhance the joint force between the surface 43 y of the second lead wireguide part 43 gb and the lead wire 10 a of the capacitor 10.

The lead wire 10 a of the capacitor 10, positioned in the groove 43 d,is preferably fixed by the adhesive (not shown) applied to the groove 43d. Thereby, it becomes possible to enhance the joint force between thegroove 43 d and the lead wire 10 a of the capacitor 10.

Next, a description will be given of the connection configuration of thelead wire 10 a of the capacitor 10 and the lead wire 6 a of the voicecoil 6, below.

The lead wire 6 a drawn from the voice coil 6 is inserted into thepenetration hole 12 h of the annular member 12 to be directed to theacoustic radiation direction Y1. Further, the lead wire 6 a is drawn tothe surface 43 y of the second lead wire guide part 43 gb. Then, the endportion of the lead wire 6 a of the voice coil 6 is directly andelectrically connected to the lead wire 10 a of the capacitor 10 drawnto the surface 43 y of the second lead wire guide part 43 gb. Inaddition, the connection part between the end portion of the lead wire 6a of the voice coil 6 and the lead wire 10 a of the capacitor 10 aresoldered by a solder 70.

The wiring configuration of the lead wire 10 b of the capacitor 10 willbe explained below.

The lead wire 10 b drawn from the capacitor 10 is guided to the otherbent part 43 gc positioned on the side of the central axis L1, of thepair of bent parts 43 gc provided on the back surface 43 x of the firstlead wire guide part 43 ga from the back surface 43 x of the capacitorfixing part 43 b, and is outwardly bent at the other bent part 43 gc tobe guided to the projecting guide part 43 gd along the back surface 43 xof the flange part 43 positioned in the vicinity of the first lead wireguide part 43 ga. Then, the lead wire 10 b, supported by the projectingguide part 43 gd, is guided to the speaker terminal mounting part 43 ato be electrically connected to the speaker terminal 11 b mounted on thespeaker terminal mounting part 43 a.

Next, a description will be given of the speaker device 100 having theconnection configuration between the lead wire 10 a of the capacitor 10and the lead wire 6 a of the voice coil 6, which is the characteristicof the embodiment.

In the speaker device 100 according to the embodiment of the presentinvention, the frame 4 has the lead wire fixing part 43 k for fixing thelead wire 10 a drawn from the capacitor 10, and the lead wire 10 a ofthe capacitor 10 is fixed to the lead wire fixing part 43 k to bedirectly and electrically connected to the lead wire 6 a of the voicecoil 6.

Thereby, even if the vibration is transmitted to the frame 4 at the timeof driving the speaker device 100, the lead wire 10 a of the capacitor10 never vibrates or moves. Therefore, it can be prevented that the leadwire 10 a of the capacitor 10 pulls the lead wire 6 a of the voice coil6. Thus, it can be prevented that the lead wire 10 a of the capacitor 10and the lead wire 6 a of the voice coil 6 are cut. In addition, sincethe lead wire 6 a of the voice coil 6 is never pulled on the side of thelead wire 10 a of the capacitor 10, it can be also prevented that thevoice coil 6 is pulled on the side of the lead wire 10 a of thecapacitor 10. Hence, it can be suppressed that the movement of the voicecoil 6 (vibration occurring when the sound current is inputted) isprevented at the time of driving the speaker device 100.

In the configuration, the lead wire 10 a of the capacitor 10 serves asthe speaker terminal lug, and it becomes possible to electricallyconnect the lead wire 10 a of the capacitor 10 and the lead wire 6 a ofthe voice coil 6 without the speaker terminal lug included in thespeaker device according to Patent References-1 to 3. Thereby, the costof the speaker device 100 can be reduced by the cost of the additionalterminal lug.

In this embodiment, the capacitor 10 is fixed to the capacitor fixingpart 43 b. Therefore, even if the vibration is transmitted to the frame4 at the time of driving the speaker device 100, the capacitor 10 neverpulls the lead wire 10 a of the capacitor 10. Thus, the lead wire 10 aof the capacitor 10 never vibrates or moves. Thereby, it can beprevented that the lead wire 10 a of the capacitor 10 pulls the leadwire 6 a of the voice coil 6.

In addition, in this embodiment, the lead wire 10 a drawn from thecapacitor 10 is guided into the insertion hole 43 h along the backsurface 43 x of the first lead wire guide part 43 ga, positioned in thedirection reverse to the acoustic radiation direction Y1, and is bent inthe acoustic radiation direction Y1 to be inserted to the insertion hole43 h. Then, the lead wire 10 a is drawn to the surface 43 y of thesecond lead wire guide part 43 gb, positioned in the acoustic radiationdirection Y1, and is guided into the groove 43 d along the surface 43 yof the second lead wire guide part 43 gb. The end portion 10 aa of thelead wire 10 a of the capacitor 10 is bent in the direction reverse tothe acoustic radiation direction Y1 to be fixed into the groove 43 d. Ina preferred example, the lead wire 6 a of the voice coil 6 is directlyand electrically connected to the part of the lead wire 10 a of thecapacitor 10 drawn to the surface 43 y of the second lead wire guidepart 43 gb.

The lead wire 10 a of the capacitor 10 is fixed by the insertion hole 43h and the groove 43 d arranged opposite to the insertion hole 43 h, bothof which sandwich the second lead wire guide part 43 gb. Thereby, evenif the vibration is transmitted to the frame 4 at the time of drivingthe speaker device 100, the lead wire 10 a of the capacitor 10 nevervibrates or moves. Therefore, it can be prevented that the lead wire 10a of the capacitor 10 pulls the lead wire 6 a of the voice coil 6.

In this embodiment, the lead wire 10 a drawn from the capacitor 10 isguided to the bent part 43 gc positioned on the outside with respect tothe central axis L1, of the pair of bent parts 43 gc provided on theback surface 43 x of the first lead wire guide part 43 ga from the backsurface 43 x of the capacitor fixing part 43 b, and is bent on theoutside at the bent part 43 gc. Further, the lead wire 10 a is guided tothe insertion hole 43 h along the back surface 43 x of the first leadwire guide part 43 ga. Thereby, even when, in some shapes of the flangepart 43 of the frame 4, the lead wire 10 a drawn from the capacitor 10,straightly extending, cannot be guided to the insertion hole 43 hbecause of probability of the short circuit with the lead wire 10 a, itbecomes possible that the lead wire 10 a drawn from the capacitor 10 isbent in the direction of the insertion hole 43 h at the bent part 43 gcand is rounded to be securely guided into the insertion hole 43 h.

In addition, since the lead wire 10 a drawn from the capacitor 10contacts the bent part 43 gc and is bent, it can be prevented that thevibration energy to the capacitor fixing part 43 b is transmitted bydispersing the vibration energy transmitted from a tinsel cord (notshown) and the frame 4 to the bent part 43 gc, it can be suppressed thatthe vibration energy is transmitted to the capacitor fixing part 43 b.Further, it can be suppressed that the capacitor 10 slips out of thecapacitor fixing part 43 b.

In this embodiment, the capacitor 10 has the pair of lead wires 10 a and10 b, and the pair of bent parts 43 gc are provided on the back surface43 x of the first lead wire guide part 43 ga with the predeterminedspace. The lead wire 10 a of the capacitor 10 is bent on the outside atthe bent part 43 gc positioned on the outside with respect to thecentral axis L1. Further, the lead wire 10 a is guided to the insertionhole 43 h along the back surface 43 x of the first lead wire guide part43 ga with the predetermined space with respect to the lead wire 10 b ofthe capacitor 10. Meanwhile, the lead wire 10 b of the capacitor 10 isbent on the outside at the other bent part 43 gc positioned on the sideof the central axis L1, and is guided to the projecting guide part 43 gdalong the back surface 43 x of the flange part 43, positioned in thevicinity of the first lead wire guide part 43 ga with the predeterminedspace with respect to the lead wire 10 a of the capacitor 10. Therefore,the short circuit between the lead wire 6 a of the voice coil 6 and thelead wire 10 b of the capacitor 10 can be prevented by the pair of bentparts 43 gc provided with the predetermined space.

The lead wire 10 b drawn from the capacitor 10 contacts the bent part 43gc and the projecting guide part 43 gd, and is bent. Therefore, bydispersing the vibration energy transmitted from the tinsel cord (notshown) and the frame 4 to the bent part 43 gc and the projecting guidepart 43 gd, it can be suppressed that the vibration energy istransmitted to the capacitor fixing part 43 b. It can also be suppressedthat the capacitor 10 slips out of the capacitor fixing part 43 b. Itcan be further suppressed that the joint force with the speaker terminal11 b weakens and wiring cut occurs.

In this embodiment, the connection part between the lead wire 10 a ofthe capacitor 10 and the lead wire 6 a of the voice coil 6 is preferablysoldered. Thereby, it securely becomes possible that the lead wire 6 aof the voice coil 6 is electrically connected to the lead wire 10 a ofthe capacitor 10.

In the present invention, by applying the wiring configuration of thelead wire 6 a of the voice coil 6 according to the above-mentionedembodiment to the tinsel cord (not shown) electrically connected to thelead wire 6 a of the voice coil 6, the lead wire 10 a of the capacitor10 and the tinsel cord may be directly and electrically connected.

Also, in the present invention, by providing a guide part (e.g., agroove) for guiding the lead wire 10 a of the capacitor 10 on the backsurface 43 x of the capacitor fixing part 43 b, the surface 43 y or theback surface 43 x of the first lead wire guide part 43 ga, and thesurface 43 y of the second lead wire guide part 43 gb, the lead wire 10a of the capacitor 10 may be guided.

In this embodiment, the frame 4 has only the capacitor fixing part 43 b,but the present invention is not limited to this. Namely, in the presentinvention, the frame 4 may have a coil fixing part for fixing variouskinds of coils and a resistor fixing part for fixing various kinds ofresistors, in addition to the capacitor fixing part 43 b.

In this case, the frame 4 has the lead wire fixing part (correspondingto the lead wire fixing part 43 k) for fixing the lead wire (not shown)drawn from the various kinds of coils or the resistors, and the leadwire of the various kinds of coils or resistors is fixed to the leadwire fixing part to be directly and electrically connected to the leadwire 6 a of the voice coil 6.

Thereby, even if the vibration is transmitted to the frame 4 at the timeof driving the speaker device 100, the lead wire of the various kinds ofcoils or resistors never vibrates or moves. Thus, it can be preventedthat the lead wire of the various kinds of coils or resistors pulls thelead wire 6 a of the voice coil 6. Hence, it can be prevented that thelead wire of the various kinds of coils or resistors and the lead wire 6a of the voice coil 6 are cut. In addition, since the lead wire 6 a ofthe voice coil 6 is never pulled on the side of the lead wire of thevarious kinds of coils or resistors, it can be prevented that the voicecoil 6 is pulled on the side of the lead wire of the various kinds ofcoils or resistors. Therefore, at the time of driving the speaker device100, it can be suppressed that the movement (vibration occurring whenthe sound current is inputted) of the voice coil 6 is prevented.

In the configuration, since the lead wire of the various kinds of coilsor resistors serves as the speaker terminal lug, it becomes unnecessaryto provide the speaker terminal lug included in the speaker deviceaccording to Patent References-1 to 3. The lead wire of the variouskinds of coils or resistors and the lead wire 6 a of the voice coil 6can be electrically connected. Thereby, the cost of the speaker device100 can be reduced by the cost of the additional terminal lug.

In this embodiment, the various kinds of coils or resistors are fixed tothe coil fixing part or the resistor fixing part, respectively. Hence,even if the vibration is transmitted to the frame 4 at the time ofdriving the speaker device 100, the various kinds of coils or resistorsnever pull the lead wire of the various kinds of coils or resistors.Therefore, the lead wire of the various kinds of coils or resistorsnever vibrates or moves. Thereby, it can be prevented that the lead wireof various kinds of coils or resistors pulls the lead wire 6 a of thevoice coil 6.

[Modification]

In some specifications of the speaker device, the insertion hole 43 hcan be formed at the lead wire fixing part 43 k of the frame 4, but thegroove 43 d cannot be provided due to the limit of the space in somecases. In this case, by changing the shape of the insertion hole 43 h,the lead wire 10 a of the capacitor 10 can be fixed by only theinsertion hole 43 h.

Now, a description will be given of other form of the insertion hole 43h according to a modification, with reference to FIG. 7A. FIG. 7A is across-sectional view of a main part in the vicinity of the lead wirefixing hole (corresponding to the insertion hole 43 h) of the lead wirefixing part 43 k, according to a modification.

First, a configuration of the lead wire fixing hole 43 hx according tothe modification will be described below.

The lead wire fixing part 43 k has the lead wire fixing hole 43 hx forfixing the bent lead wire 10 a of the capacitor 10. In the presentinvention, it is not necessary that the lead wire fixing hole 43 hx isprovided at the lead wire fixing part 43 k. Namely, the lead wire fixinghole 43 hx may be provided at any position at the flange part 43 of theframe 4. The lead wire fixing hole 43 hx penetrates in the acousticradiation direction Y1 (not shown; corresponding to the upper part inFIGS. 7A to 7C). The lead wire point supporting part 43 ha (a part shownby a broken-lined area) for supporting the end portion 10 aa of the leadwire 10 a of the capacitor 10 is provided in the lead wire fixing hole43 h. The lead wire point supporting part 43 ha has a step-statecross-section.

Next, a description will be given of the fixing configuration of thelead wire 10 a of the capacitor 10 in the lead wire fixing hole 43 hx.

The lead wire 10 a drawn from the capacitor 10, which is bent in thelead wire fixing hole 43 hx, is fixed into the lead wire fixing hole 43hx.

Concretely, the lead wire 10 a drawn from the capacitor 10 is guided tothe lead wire fixing hole 43 hx along the back surface 43 x of the leadwire fixing part 43 k, positioned in the direction reverse to theacoustic radiation direction Y1, and is bent in the acoustic radiationdirection Y1 to be inserted to the lead wire fixing hole 43 hx. Further,the lead wire 10 a is arranged in the lead wire fixing hole 43 hx toform the projecting shape in the acoustic radiation direction Y1. Then,the end portion 10 aa of the lead wire 10 a of the capacitor 10 issupported by the lead wire point supporting part 43 ha in the lead wirefixing hole 43 hx. Thereby, the lead wire 10 a of the capacitor 10arranged in the lead wire fixing hole 43 hx is fixed by the lead wirepoint supporting part 43 ha and a surface 43 hb opposite to the leadwire point supporting part 43 ha.

Now, a description will be given of an example of the method of fixingthe lead wire 10 a of the capacitor 10 to the lead wire fixing hole 43hx, with reference to FIGS. 7B and 7C.

First, as shown in FIG. 7B, the lead wire 10 a drawn from the capacitor10 extends along the back surface 43 x of the lead wire fixing part 43 kto step over the lead wire fixing hole 43 hx. Next, as shown in FIG. 7B,a jig 80, which has a end portion 80 a having a step-state cross-sectionand able to be inserted into the lead wire fixing hole 43 hx, isprepared. Then, as the jig 80 is made to move in an arrow direction (inthe acoustic radiation direction Y1), the jig 80 is inserted into thelead wire fixing hole 43 hx so that the end portion 80 a and the leadwire point supporting part 43 ha engage with each other, as shown inFIG. 7B. Next, the jig 80 is withdrawn from the lead wire fixing hole 43hx to the direction reverse to the acoustic radiation direction Y1.Thereby, the lead wire 10 a of the capacitor 10 is fixed into the leadwire fixing hole 43 hx to form the projecting shape in the acousticradiation direction Y1. According to this method, the lead wire 10 a ofthe capacitor 10 can be easily fixed into the lead wire fixing hole 43hx.

Next, the connection configuration of the lead wire 10 a of thecapacitor 10 and the lead wire 6 a of the voice coil 6 will be explainedbelow.

The lead wire 10 a of the capacitor 10 exposed on the side of thesurface 43 y of the lead wire fixing part 43 k, positioned in theacoustic radiation direction Y1, is directly and electrically connectedto the lead wire 6 a drawn from the voice coil 6 at the positioncorresponding to the lead wire fixing hole 43 hx. In the modification,the drawing direction of the lead wire 6 a of the voice coil 6 is sameas that of the lead wire 10 a of the capacitor 10. However, the drawingdirections of them may be different. In addition, the connection partbetween the lead wire 10 a of the capacitor 10 and the lead wire 6 a ofthe voice coil 6 are soldered.

In the modification, the lead wire 10 a of the capacitor 10 is fixedinto the lead wire fixing hole 43 hx by the lead wire point supportingpart 43 ha and the surface 43 hb opposite to the lead wire pointsupporting part 43 ha. Further, the lead wire 10 a of the capacitor 10exposed on the surface 43 y of the lead wire fixing part 43 k isdirectly and electrically connected to the lead wire 6 a of the voicecoil 6 at the position corresponding to the lead wire fixing hole 43 hx.

Thereby, even when the space of the lead wire fixing part 43 k is notenough, the lead wire 10 a of the capacitor 10 can be securely fixedinto the lead wire fixing hole 43 hx.

In the configuration, since the lead wire 10 a of the capacitor 10serves as the speaker terminal lug, it becomes unnecessary to providethe speaker terminal lug included in the speaker device according toPatent References-1 to 3. Thus, the lead wire 10 a of the capacitor 10and the lead wire 6 a of the voice coil 6 can be electrically connected.Thereby, the cost of the speaker device 100 can be reduced by the costof the additional terminal lug.

In the configuration, even if the vibration is transmitted to the frame4 at the time of driving the speaker device 100, the lead wire 10 a ofthe capacitor 10 never vibrates or moves. Therefore, it can be preventedthat the lead wire 10 a of the capacitor 10 pulls the lead wire 6 a ofthe voice coil 6. Hence, it can be prevented that the lead wire 10 a ofthe capacitor 10 and the lead wire 6 a of the voice coil 6 are cut. Inaddition, since the lead wire 6 a of the voice coil 6 is not pulled onthe side of the lead wire 10 a of the capacitor 10, it can be preventedthat the voice coil 6 is pulled on the side of the lead wire 10 a of thecapacitor 10. Thus, at the time of driving the speaker device 100, itcan be suppressed that the appropriate movement of the voice coil 6 isprevented.
